Frequently Asked Questions
What is a healthy BMI?
A healthy BMI is between 18.5 and 24.9. This range is associated with the lowest health risks. However, BMI doesn't account for muscle mass, bone density, or fat distribution.
Is BMI accurate for athletes?
BMI can be misleading for athletes and bodybuilders who have high muscle mass. They may have a high BMI but low body fat. In such cases, body fat percentage is a more accurate measure.
What is the BMI formula?
BMI = Weight (kg) / [Height (m)]². For imperial: BMI = 703 × Weight (lbs) / [Height (inches)]². It was developed by Belgian mathematician Adolphe Quetelet in the 1830s.
